As the issues such as safety, hygiene, convenience of school facility from the perspective of living environment for students and teachers arise as an important task in recent, there is increasing concern for resting convenience facility in school. In recent, the government is planning to change middle high school into the departmental classroom system. The departmental classroom system refers to the school operation system in which the classroom is structured as a subject-specialized classroom and the students move to the classroom according to their class schedules. This departmental classroom system is advantageous in that each subject can be equipped with professional facilities or preparations; the usage rate of the classroom can be enhanced; the common study space or living space can be used substantially; the school can plan and operate its own specialized space. On the contrary, it has the weaknesses that there is need to prepare the home base for the guidance of the class or student guidance; there is need for the facilities including personal lockers. Thus, the departmental classroom system requires the space expansion for home base or the resting convenience space for students and thus has to provide various spaces. Under this background, it is also important to check and plan the resting space for the schools. Therefore, this study is aimed to examine and analyze the arrangement location and space Layout of the resting convenience space among school facilities to propose the architectural data for future resting/convenience spaces for the schools.

This study analyzes the domestic kindergarten attached to elementary school, and that is to present the basic data to be established in the future on the basis of the problems seen in kindergarten attached to elementary school analysis of construction planning. For this study, selecting 10 kindergartens in Hwaseong, Gyeonggi-do, and the selected spatial configuration of kindergarten. And then, analyzes Space Organization, Circulation Plan, Area Distribution, Spatial Hierarchy of them. The results were as follows. 1) The current kindergarten attached to elementary school is associated with the most elementary building planes are independent. 2) Most of them don't have space for secondary activities such as playroom or hallway space between the classrooms and the entrance. 3) Interior space is composed of educational space, service space, administrative space. 4) Kindergarten attached to elementary school should plan increase the area because it is small scale there are a lot of dead space. 5) The main users of kindergarten children should be planned simultaneously in a space that is used along with the teacher. Such a kindergarten attached to elementary school in order to be implemented in construction and environmental characteristics of the kindergarten curriculum developers and juxtaposition of kindergarten teachers and architects such exchanges should be made a doctor of the tripartite briskly.

본 연구는 중학교 자유학기제 전면 시행에 따른 학습활동 공간, 학생자치 등 학생활동 공간, 학생들간의 소통 및 지역사회와의 공동체 형성을 위한 공간 등으로 학교 식생활관의 식당을 다목적공간으로 활용할 수 있는 방안을 위한 교육공동체의 인식을 분석하는데 목적을 두고 있다. 이에 본 연구에서는 학교 식당의 다목적 공간 활용에 관한 인식조사 하였으며 분석 결과 첫째, 식당 공간을 운영하는 중학교의 거의 대부분이 식사 이외의 다른 용도로 활용한 경험이 없는 것으로 나타났으며, 둘째, 다른 용도로 활용하지 않은 이유는 위생관리의 어려움이 가장 많은 것으로 분석되었다. 셋째, 학교 식당공간의 일부를 유리벽이나 가변형의 벽체로 구획하여 다른 용도로 사용하는 방안에 대하여 찬성하는 이유는 중학교 자유학기제 활용 등 교육과정 운영을 위한 학습 공간 지원과 학생들간의 소통 공간 확보를 위해서라고 분석되었다. 넷째, 식당공간의 다목적으로 활용 가능한 용도로는 영양 식생활 교육 공간이 가장 많았고, 다음으로 자유학기 등 교육과정 운영, 학생 간의 소통 공간 순으로 나타났다. 다섯째, 학교 식당공간을 다용도로 활용 시 공간 조성 방향에 대해서는 공간의 가구는 효율적인 공간 활용이 가능하도록 이동과 조합이 편리한 것을 설치하는 것이 중요한 것으로 나타났다.

As high schools implement credit completion system these days, concerns about the dissolution of classes, which are the original stable groups of studying and living, and the instability of the basal space, is growing due to the extended operation of moving optional classes. The purpose of this research is to understand the effect that environmental features of the basal space within the school and the operation method have on the students' space use and formation of attachment place within the school. For this, the main activity places, attachment places, school life satisfaction and others were investigated at 2 Japanese credit-based comprehensive high schools, which are different in the physical environmental features of school buildings. Based on this, a quantitative analysis about the distribution of activity places and attachment places was implemented. The space use features for each student attribute were compared, and the school life satisfaction for each type of attachment place formation was analyzed. As a result, the change of the territorial consciousness about the class space according to the implementation of moving optional classes could be understood. And it was confirmed that the students' space using behavior and place evaluation change according to the physical environmental feature of the class space and common space, and that this is affecting the life satisfaction of students.

A novel space vector modulation strategy in the non-orthogonal three-dimensional coordinate system for multi-level three-phase four-wire inverters is proposed in this paper. This new non-orthogonal three-dimensional space vector modulation converts original trigonometric functions in the orthogonal three-dimensional space coordinate into simple algebraic operations, which greatly reduces the algorithm complexity of three-dimensional space vector modulation and preserves the independent control of the zero-sequence component. Experimental results have verified the correctness and effectiveness of the proposed three-dimensional space vector modulation in the new non-orthogonal three-dimensional coordinate system.

School Design in the future will be more important on exterior space plan. However, there is no specific definition or boundary regarding exterior space, and related regulations and guides define the essential factors only. The purpose of this study is to have a guideline for the concept of exterior space in elementary school buildings, and deducted strong and weak points by evaluating exterior space based on each business methods. A result of this study can be suggest what improvements should be made on exterior space design of elementary school buildings by comparative analysis of positive and weak points for each evaluation factors.

Kyung Hee University has been developing a CubeSat for the space science mission called SIGMA (Scientific cubesat with Instrument for Global Magnetic field and rAdiation), which includes TEPC (Tissue Equivalent Proportional Counter) and a magnetometer. SIGMA has a 3-unit CubeSat, and the weight is about 3.2 kg. The main payload is TEPC which can measure the Linear Energy Transfer (LET) spectrum and calculate the equivalent dose for the complicated radiation field in the space. The magnetometer is a secondary payload using a miniaturized fluxgate magnetometer. We expect it to have a 1 nT resolution in the dynamic range of ${\pm}65535$ nT. An Attitude Control System (ACS) spins the SIGMA spacecraft 4 rpm with the spin axis perpendicular to the ecliptic plane. Full duplex communication is consists of VHF uplink and S-band and UHF downlink. In this paper, we introduce the system design and the scientific purpose of the SIGMA CubeSat mission.

A novel Virtual Space Vector (VSV) modulation strategy for complete control of potential neutral point (NP) issues is proposed in this paper. The neutral point potential balancing problems of multi-level converters, which include elimination of low frequency oscillations and self-balancing for NP dc unbalance, are investigated first. Then a set of improved virtual space vectors with dynamic adjustment factors are introduced and a multi-objective optimization algorithm which aims to optimize these adjustment factors is presented in this paper. The improved virtual space vectors and the multi-objective optimization algorithm constitute the novel Virtual Space Vector modulation. The proposed novel Virtual Space Vector modulation can simultaneously recover NP dc unbalance and eliminate low frequency oscillations of the neutral point. Experiment results show that the proposed strategy has excellent performance, and that both of the neutral point potential issues can be solved.
